Lettere Patent No. 94,229, dated August 31, 1869.

i IMPROVED TRACE-BUCKLE.

The Schedule referred to in these Letters Patent and making of the same.

To all whom lit may concern. t

Beit known that I, J onu H. Msmngof Columbus, in the county of Franklin,- and- State of Ohio, have invented a new and. improved Trace-Buckle; and I do hereby declare .that the following is a full,

clear, and exact description thereof, reference being.

had to the accompanying drawings, making part of this specifica-tion, in which.- i c Figure l is a perspective view, showing my yirnproved buckle, with a trace and a llames-tug applied to it.

Figure 2 is a front view of the buckle, without the trace or hames-tug.

Figure 3 is a longitudinal section, taken centrally through the buckle.

Figure 4 is a longitudinal section of the buckle, having a trace and llames-tug applied to it.

Figure 5 is a cross-section through the buckle.

Similar letters of reference indicate corresponding parts in the several figures.

My object is to so construct a trace-buckle that the crossbar, to which the tongue for holding lthe trace is applied, shall be movable, andshall serve, in conjunc- `tion with the fixed cross-bar, to which the harnes-tug is fastened, as a means for clamping the trace atand near the point where the tongue enters it, thereby relieving the trace from undue strain where it would b e most liable to give way, and at the same time pro-I u'ding for'readilydetaching the trace from its tongue when desired, as will be hereinafter explained.

To enable others skilled in the art to understand my invention, I will describe its construction and operation.

In the accompanying drawings- D represents a rectangular buckle-trame, the front side of which is flat, and adapted to receive a handsome iinish.

The frame l) is oblong, and it isprovided with side loops, F, and an end loop, G, for receiving the'wellknown harness-straps.

Near the middleof the length of this buckle-trame is a cross-bar, J, which may be made round, but which I prefer to make of the wedge-form shown iu ligs. 3 and 4, for a reason to behereinaiter explained.

Taken transversely this bar J is parallel to the fiat surface of the frame D. It extends across between the two portions au which are formed on the back sides of the longitudinal bars of the frame, as shown clearly in 5.

Erepresents a slide, which is made of malleable metal, with lips, e e', on its ends, and which is applied to the parallel longitudinal bars of the buckle-frame, by adjusting ithetween these bars, and then setting ont the lips e e', as shown in iig. 5. This connects the slide to the buckle-frame permanently, but allows it to be moved in a direction with respect to the length of this frame. n

On the back side of the slide, a stud or tongue, g, is formed, which is designed to enter holes made through the trace, as shown in g. 4, and prevent the trace C from casually slipping.

The llames-'tug A is secured to the wedge-shaped A cross-barJfas'shown in iig. 4, and passes on" beneath the slide E, so that when the trace is applied to the buckle, it is between the slide E and haines-tug A.

Fig. 4 of the accompanying drawings shows-the condition of-things in the buckle when the trace and haines-tug are under tension,

It will be seen that the parts E .and J are drawn toward one another, and that the trace is clamped and compressed between the said parts its' entire width.

The width given to the cross-bar J will have the effect of holding the tug-strap in its place when the trace is slack,and preventing the trace from becoming casually'detached from the tongue y.

By bevelling the said cross-bar J, as shown, the

slide E can be drawn nearer to it, and will clamp or contine the trace more iirmly.

Broadly considered, I do n ot claim a sliding or adinstable buckle-tongue, as this is not new. l

That I claim as new, and desire to secure by Letters Patent, is-

A slide, E, applied to the bucklerfra'me D, and con- A structed with a tongue, y, in combination with a crossbar, J, substantially as described.
